面向节能的冲压车间调度优化方法

Optimization method of energy saving for stamping workshop scheduling

合理的车间调度是降低制造业生产能耗的有效策略之一.结合冲压车间生产特性,分析了冲压车间中冲压件加工过程的能耗,以完工时间最小和车间总能耗最低为目标,建立了面向冲压车间的优化调度模型,在模型中考虑冲压件的批量以及运输能耗.采用遗传模拟退火算法对模型进行求解,并对4种批量冲压件的加工进行了实例分析.结果显示：采用优化调度方案与传统调度方案相比,在完工时间增加了2.56%的基础上,车间总能耗降低了5.25%,平衡了完工时间与总能耗;同时,考虑运输能耗的调度将有助于决策者选择更加节能的调度方案.研究结果验证了所建立模型的可行性及有效性.

Reasonable workshop scheduling is one of the effective strategies to reduce energy consumption in manufacturing industry. Ac-cording to the production characteristics of stamping workshop,the energy consumption in the machining process of stamping parts was an-alyzed,and the optimal scheduling model for stamping workshop considering the batch of stamping parts and transportation energy con-sumption was established taking the minimized completion time and total energy consumption of workshop as the optimization objectives. Fur-thermore,the model was solved by genetic-simulated annealing algorithm,and the processing of four types of batch stamping parts was ana-lyzed with examples. The result shows that comparing with the traditional scheduling scheme,the completion time of the optimal scheduling scheme increases 2.56%,and the total energy consumption of workshop decreases 5.25%. Thus,the completion time and total energy con-sumption are up to balance. At the same time,the scheduling considering transportation energy consumption can help decision-makers to choose a more energy-efficient scheduling scheme,and the feasibility and validity of the established model is verified by the research results.
